CORPORATION OF NEW YORK CALCULATING DEVICE Application filed January 30, 1925. Serial No. 5,717.

This invention relates to calculating devices and more particularly to a device for computing the number of articles in a mass of articles of like weight.

Counting scales, for determining the number of articles in a mass of articles of like weight, are in common use but these devices comprise weighing mechanism for the mass of articles to be count-ed and this adds materially to the complications of the mechanism and to the cost of producing the same, this being particularly true in the case of high capacity mechanisms, that is, mechanisms designed to handle masses of articles weighing from one hundred pounds up. There are many instances where a manufacturer or other user has occasion at more or less fre quent intervals to count heavy masses of articles but is already equipped with high capacity weighing scales and the necessity for counting does not arise sufliciently often to justify the large expenditure which would be necessary to install a high capacity counting scale.

One object of the present invention is to provide asupplementary device for use in connection with the regular weighing scale for computing the number of like articles in a mass of such articles.

i l further object of the invention is to provide such a device which will be readily portable so that it can be moved easily from one location to another; and which will be of such a character that it will not be necessary to accurately level the same prior to use.

A further object of the invention is to provide such a device which may be either semiautomatic in its operation or wholly manual in its operation.

A further object of the invention is to provide such a device which will be simple in its operation and can be quickly and easily manipulated to effect a computation.

Other objects of the invention will appear as the mechanism is described in detail.

In these drawings I have illustrated one embodiment of my invention and have shown the same as a counting device for computing the number of parts in a mass of articles of like weight but it will be understood that the mechanism may take various forms and may be used for various purposes without departing from the spirit of the invention.

In that particular embodiment here illustrated the device comprises a base having mounted thereon and extending upwardly therefrom a main supporting frame consisting of front and rear members 2 and 3. Each of these members comprises two upright standards or end members connected by upper and lower tie bars 4 and 5. The front and rear members are, in the present in stance, each formed from a sin le sheet of metal and have their end portions bent one toward the other to provide vertical flanges 6 which are rigidly secured one to the other by plates 7 The tie bars 4 and 5 of the front and rear members of the frame are rigidly connected one to the other, respectively, by spacing plates 8 and 9, which are flanged at their edges and rigidly secured to the respective tie bars by rivets or otherwise, these spacing plates being provided with openings or being of skeleton formation to permit the passage therethrough of various parts of the operating mechanism, as will hereinafter appear. The supporting frame as a whole is here shown as rigidly secured to the base by means of tie plates 10 provided at their ends with lugs 11 which extend through openings in the vertical standards of the front and rear frame members and these plates are secured to the base by means of bolts 12 extending through the same and through the base. This frame, together with the base, serves as a support for the several operating parts of the mechanism, and the frame and the parts carried thereby are enclosed in a housing or cabinet consisting of front and rear plates 13 and 14 connected one to the other by end plates 15 and provided with a top plate 16,

the several plates being, in the present instance, formed of sheet metal and secured one to the other by meansfof screws. The front plate 13 has its intermediate port-ion cut away to provide an opening 17 which is closed by a plate of glass 18 through which the indicating members and their associated parts may be. viewed. This cabinet is secured to the base by means of lugs 19 and screws 20.

The computing mechanism comprises two indicating members mounted for movement relatively one to the other and in the computation or counting of parts one of. these indicating members is adjusted to a position corresponding to the weight of the mass of ar icles to be counted and the other is adjusted to a position corresponding to the weight of a unit of the articles to be counted, this unit to consist of one or more articles, and the relative positions of the two indicating members indicates the result of the computation, that is, the number of articles in the mass. In the present arrangement the two indicating members are moved into intersecting positions so that one will indicate a certain graduation on the other, As has been stated the present device is designed for use in connection with and is supplemental to an ordinary weighing scale and instead of providing the same with a load weighing mechanism for the mass of articles to be counted, means are provided whereby the indicating member, which is controlled according to the weight of the mass, is adjusted manually to a position corresponding to the weight of the mass, which has been previously determined by the use of a regular weighing scale. In the particular embodiment of the invention here illustrated the indicating member which is positioned according to the weight of the mass is in the form of a chart 21 provided with a longitudinally extending series of graduations associated with which are a plurality of series of designationsor figures, each series being significant of the value of the graduations when a unit of a certain value is employed. As shown in Fig. 6 there are six: series of these designations numbered 1, 2, 5, 10, 25 and 50, and the figures of the respective series indicate the value of the graduations when the computation is based on a unit consisting of 1, 2, '5, 10, 25 or 50, parts. @bviously the unit may consist of any desired number of parts and those indicated on the present chart have been arbitrarily selected. The second or units indicating member is preferably pivotally mounted and is here shown in the form of a wire 22 carried by a supporting arm 23 which is pivotally mounted near the upper end of the chart 21', as will hereinafter appear. The indicator wire 22 is so arranged with relation to the chart 21 that when both indicating members are in their Zero positions this wire will be parallelwith and lie directly in front of the center line of the series of graduations on the chart. When both indicating members have been moved from their Zero positions the units indicator will extend at an angle to and intersect the chart, the principal graduations on the chart which is intersected by the units indicator depending upon the relative positions of the wvliich application I have employed separate weighing mechanisms for actuating the respective indicating members.

As here shown the chart or load indicating member 21 is moved in a right line transversely to its length and to this end I have mounted the same upon a carriage and have rovided manually operated means for adustingthatcarriage. Preferably, the carriage comprises a supporting member or plate 2% provided at its front and rear edges with rollers 25 and 26 which travel respectively on tracks 2'? and 28 which are supported by the base 1 and are here shown as angle bars havin g their horizontal flanges rigidly secured to studs 29 depending from the top wall of the base. In order to provide a three point support for the carriage the body or supporting plate 24: thereof is made substantially triangular in shape with its wide edge at the rear and this wide edge is provided with two rollers, 25, while the front edge is provided with a single roller, 26. The rollers 25 at the rear side of the carriage are grooved to receive the upper edge of the track 27, which is preferably beveled, and thus hold the carriage against lateral displacement with respect to the tracks. The, rollers at the rear edge only are grooved and the front roller 26 has a flat surface engaging the track 28 so that this roller is not held in fixed lateral relation to the track but may adjust itself thereto should there be any variations in the spacing of the two tracks one from the other or any irregularities in the shape of either track. Mounted on the carriage is an upright bracket or standard 30 which is preferably channel shaped in cross section and to which the chart 21 is rigidy but adjustably secured. As here shown, the chart 21 has secured to the upper end thereof and spaced from the rear thereof a downwardly extending lug 31 which is provided with an aperture to receive a flanged stud 32 which is mounted in the bracket 30 and is arranged substantially coincident with the axis of the pivoted indicating member 22. The lug 31 lies between the lateral flanges of the channel shaped bracket 30 but has suflicient clearance to permit of a slight pivotal movement thereof to enable the chart to be adjusted with re lation to the pivoted indicating member to properly aline these parts. The lower portion of the chart 21 has depending therefrom a lug 33 also arranged between the lateral flanges of the channel shaped bracket and capable of a slight lateral movement between said flanges. This lug 33 is provided with an enlarged opening or slot 34 through which extends a headed screw 35 which is screw threaded into the back wall of the bracket 30 and the head of which serves to clamp the lug 33 and consequently the chart in adjusted positions. To permit very fine lateral adjustments of the chart to be effected, I have mounted in the side flanges of the bracket 30 screws 36 which extend into the channel and engage the respective edges of the lug 33, whereby the chart may be adjusted laterally with relation to the bracket or standard but will be held rigidly in its adjusted position. The chart may also be adjusted in a vertical direction, this being accomplished by slightly loosening the screw 35 and inserting the bit of a screw driver or the like between the head of the screw and the shoulder formed between the lug 33 and the body of the chart 21, to impart upward movement to the chart, or by inserting such a bit between the lower edge of the screw head and the flange 37 at the lower end of the lug 33 to force the chart downward. When the desired adjustment is secured the screw 35 is tightened to lock the chart in its adjusted position. The manually operated means for adjusting the chart may take various forms but, in the present machine, I have connected with the carriage 2s; a cable 38 which extends about guide pulleys 39 supported by and near the ends of the base 1 and which is wound about and connected with an actuating pulley or drum 40. The pulley 40 is rigidly secured to a shaft stl which is journaled in a bearing 42 depending from the top wall of the base 1, which is provided with a forwardly extending portion in which the actuating pulley or drum is mounted. The cable 38 is wound one or more times about the drum, which is preferably provided with suitable grooves to guide the cable in its movement thereon, and the cable is rigidly secured at an intern'iediate point to the drum so as to hold the same against slippage thereon. The cable may be conveniently connected with the drum by providing the latter with a recess in which is mounted a screw 43 and a washer H and the cable is carried into this recess, about the screw and beneath the washer so that by tightening down the screw the cable will be clamped rigidly to the drum, but by loosening the screw the cable may be adjusted relatively to the drum. The two ends of the cable 38 are connected one to the other by a spring 4a. which has its ends provided with hook shaped portions to engage through eyesformed in clips 45 and d6 carried by the respective ends of the cable 38. This spring serves to take up any slack in the cable and to maintain the same taut. It is desirable that the connection between the cable and the carriage 24 should be such as to rigidly hold these parts against relative displacement lengthwise of the cable but to permit the cable to have twisting movement and rising and falling movement with relation to the carriage. This is accomplished by rigidly securing to the carriage 2 a depending bracket t? which is provided with a vertical. slot 48 to embrace the clip on the cable and this clip is provided with collars 49 to provide a circumferential groove to receive the bracket 47. The collars fit sufficiently close to the faces of the bracket to hold the same against any appreciable displacement longitudinally of the cable but there is sufficient clearance to permit the cable and clip 46 to rotate about a longitudinal axis or twist in the operation of the cable and also to permit the clip to to rise and fall within the slot of the bracket.

The shaft 41 of the actuating drum 4L0 e2 tends above the top wall of the base 1 and has rigidly secured thereto an actuating knob 50 by means of which the drum may be rotated to impart movement to the carriage in either direction. The amount of movement imparted to the drum is determined according to the weight of the mass of articles to be counted and I have therefore connected with the knob 50 a pointer 51 which travels over an annular series of graduations 52 carried by a dial plate 53 rigidly secured to the top 1 all of the base, although obviously these graduations could be placed directly upon the base itself. The graduations 52 are, in the present instance, spaced to represent weights from five pounds up to five hundred pounds and when the pointer 51 is moved into alinement with any one of said graduations the chart will be moved to a position corresponding to that weight. The pointer 51 is adjustably connected with the knob so that it may be maintained in its proper position with relation to the carriage and chart, that is, when the chart is in its zero position the pointer also should be in its zero position.

' To this end the pointer 51 is formed separate from the knob and has a hub portion 54, the lower side of which is recessed to receive a washer 55 also surrounding the shaft 41. The washer is connected with the knob 50 by means of a screw 56 which extends through the knob and the hub of the pointer and is screw threaded into the washer 55, thus serving to rigidly clamp the pointer to the knob, but the opening in the pointer, through which the screw extends, is elongated so that by loosening the screw. the pointer be adjusted with relation to the knob and consequently with relation to the actuating drum and the chart. Suitable means are provided for limiting the rotation of the drum 40 and this means is of such a character as to permit the drum and the pointer 51 to make at least a complete rotation and, further, the controlof the drum may be so regulated that when the pointer 51 is in its Zero position the chart will be in its zero position. This adjustment is made necessary by the fact that the cable 38 may at times become elongated, due not so much to the tension under which it is placed as to the kneading action which takes place in the strands of the cable where it passes around the pulleys. As shown in Fig. 4 a rod 57 is mounted in the base 1 and has its inner end screw threaded into a lug 58 depending from the top wall of the base and g has its outer portionjournale'd in suitable bearings 59 in the side wall of the base and extending beyond the same where it may be engaged by a suitable implement for rota-t-.

ing the same, such as a screw driver. Rigidly secured to this rod is a circumferential flange or collar 60 which forms a fixed but adjustable stop for the drum. Loosely mounted on the shaft 41 and confined between the drum and the bearing 42 is a stop arm 61 having at its outer end two stop lugs 62 which are spaced apart and opposed one to theother and which are arranged on opposite sides of the stop collar'60 on the rod 57. Mounted in the top of the drum is a stud or pin63 which is so arranged that'it will engage one side or the other of the stop arm 61 when ling means is adjustable so that the movement the drum is rotated and will cause this arm to move with the 'drum until one of the stop lugs 62 engages the collar 60. The stop lugs are spaced apart a sufiicient distance to permit at least a complete rotation of the drum and, in the present instance, slightly more than a complete rotation. In the event that, due to the elongation of the cable or to other reasons, the pointer 51 and the chart 21 do not simultaneously register with their zero positions, the rod 57 is rotated to adjust the stop 60 to a position which will permitthe chart to be moved into its zero position. This adjustment will cause the pointer 51 to move beyond its zero position and after the chart has been adjusted the pointer must be loosened and adjusted to its proper zero position.

The unit indicating member 22 may be actuated automatically as by the weight of a unit on a unit receptacle suitably connected therewith, or it may be adjusted manually to a predetermined position. In the present machine T have provided both methods of adjustment. The arm 23 which carries the indicating member 22 is rigidly secured at its upper end to a pivoted supporting member 64 which is provided with a laterally ofiset portion 65 to which the arm 23 is rigidly secured. This supporting member 64 is supported by means of knife edge pivots 66 in V-bearings 67 carriedby brackets 68 extending upwardly from the tie bars 4 of the front.

and rear frame members, the pivot pin 66 being formed at the ends of a trunnion 69 rigidly mounted in the supporting frame 64.

The bearings are provided with caps 267 which'have ears 268 overlapping the ends of the respective bearings and forming end thrust bearings for the pivots.

As haslbeen stated, the indicating member or wire 22 is connectedat its lower end with the adjacent end of the arm 23 which is so 'wire is secured directly to the supporting member 64, the forwardly extending portion 65 of which is provided with a lug 141 on which ismounted a bracket 142, the bracket being preferably pivotally mounted by means of a stud or screw 143. vided at its upper end with an outwardly extending portion or flange 144 with which the wire 22. is connected- A spring 145 is preferably interposed between the wire and the bracket so as to maintain the wire constantly under tension and keep it taut and straight. The bracket 142 has at its lower end a second forwardly extending portion or flange 146 which is provided with a kerf or narrow slot 147 in which the wire 22 rests. The point of connection of the spring 145 with the bracket is slightly in the rear of the base of the slot 147 so that the tension on the spring will tend to hold the wire in the slot. The bracket ispivotally mounted to permit This bracket is prothe wire to be adjusted laterally to properly aline the same with relation to the chart and in order to secure this adjustment and retain the wire rigidly in its adjusted positions the bracket is provided with rearwardly extending lugs 148 in which are mounted screws 149 engaging the opposite sides of the fixed lug 141. By adjusting these screws the position of the bracket, and consequently of the wire may be shifted but when both screws are in contact with the lug 141 the bracket and the wire will be held rigidly in their adjusted positions. I have herein referred to the unit indicating member 22 as a wire because a metallic wire is frequently used in indicating members of this kind but it will be understood that this indicating member need not he of metal but may consist of a flexible strand or cord of any suitable character, such as silk, and such a strand would be the full equivalent of the wire. As a matter of fact in some cases it is preferable to use a nonmetallic thread because of its greater flexibility which enables it to be held taut and absolutely straight under less tension than is necessary in order to maintain a metallic thread perfectly straight.

Rigidly but adjustably connected with the supporting member 64.- is an arm which, as here shown, comprises two parallel members having hub portions 71 rotatably mounted on the trunnion 69 of the supporting member 64 and connected one to the other by pins 7 2. Cooperating with these pins are screws 73 mounted in laterally extending lugs 74 carried by the supporting member 64. By adjusting the screws 7 3 the position of the arm 70 with relation to the supporting member may be adjusted but when both screws are in contact with the respective pins 72 the arm will he rigidly held against all movement with relation to the supporting member and consequently with. relation to the unit indicating member which is carried thereby. The arm 70 is provided at its outer end with a knife edged pivot 75, here shown as arranged between the two parts of the arm. This knife edge pivot cooperates with an inverted V-bearing 76 which is pivotally connected by means of a pin 77 with a yoke 78 which in turn is secured to the upper end of a rod 79, the knife edge pivot and the pivot pin 77 serving to establish a substantially universal connection. between theyoke and the arm 70. The rod 79 connected at its lower end with a second yoke 80 which has pivotally connected therewith a stirrup 81 which in turn carries a needle point bearing 82 in which is seated a needle point pivot pin, 83 rigidly mounted in a nose iron 84 carried by'and forming a part of a lever 85. The needle pointpivot 83 is clamped in the end of the nose iron, by means of a screw 86, so as to be vertically adjustable therein and the nose iron is longitudinally adjustable in the end of the lever and is held in adjusted positions therein by means of a screw 87. The lever 85 is, in the present machine, a unit actuated member and is so connected with the unit receptacle as to be actuated thereby and to transmit the movement induced by the weight of the unitto the unit indicating member. The lever 85 is somewhat irregular in its shape, as shown in Fig. 8, and has rigidly secured thereto knife edge pivots 88 which rest in V-bearings 89 carried by brackets 90 extending upwardly from the lower tie bars 5 of the main frame. Secured to the brackets 90 and overlying the respective ends of the pivot pin 88 are caps 91 having downturned portions or cars 92 which overlap the ends of the pivot pin and form end thrust bearings therefor which will prevent the lateral displacement of the lever 85.

A unit receptacle of any suitable character may be connected with the unit actuated memher or lever 85 in any suitable manner. In the present device the unit receptacle is shown. at 93 as mounted on a pronged support 9%. which is rigidly secured to the upper end of a vertical supporting rod 95, the lower portion of which extends through the lower tie plate 9 and is connected with the lever The lever 85 is provided intermediate at its ends with an offset portion and with a short arm 96 lying parallel with said offset portion and cooperating therewith to support a pivot pin 97. The body portion of the sup porting bar 95 for the unit receptacle is in substantial alinement with the pivot pin 97 and in. order to pass the same is provided with an offset portion 98, it being noted that those portions of the bar at opposite ends of the offset portion thereof are in alinement one with the other and with the pivot pin 97. Extending upwardly from the lower portion of the bar 95 and overlapping the lower part of the offset portion 98 thereof is a plate 99 between which and the offset portion of the bar is mounted a stud 100 which is embraced by the lower loop of an S-shaped link 101 the stud being preferably grooved to receive this loop and being retained therein by a cotter pin 102. The upper loop of the S-shaped link 101 embraces a stud 103 carried by a yoke 104, the upper end of which is provided with an inverted V-bearing 105 which engages the pivot pin 97. The bar 95 is connected at its upper and lower ends with a rigidly mounted vertical bar 106 by means of links 107. As here shown, the bar 106 extends through the spacing plates 8 and 9 and is rigidly secured thereto. Each of the links 107 consists of two plates the central portions of which are rigidly connected one to the other, face to face. Each end portion of each plate of the link is offset from the body of the link, as shown at 108, and these offset portions are laterally extended to form arms 109. The outer ends of the corresponding bars with the adjacent ends of the respective links. This connection between the supporting bar and the lever is sulliciently universal in its action that the gravitational force of a unit placed in the unit receptacle 93 will be properly directed to the pivot 97 irrespective of any unnatural action which may occur in the movement of the bar 95, such as would result if the unit is placed in the receptacle 7 at one side of the center thereof. Further,

because of the universal action of this type of connection there is no tendency to displace the fulcrum pivot of the lever 85 in its bearings, and thus permit the lever toslew sidewise and to interfere with its proper operation, no matter where the unit may be placed in the unit receptacle. The links and the pins connecting the same with the vertical bars 95 and 106 have been. shown as having trunnion bearings. Should it be desired to further reduce the friction in these bearings, ball bearings may be substituted for the trunnion bearings. In Figs. 13 and 1% I have shown this typeof link equipped with ball bearings.

As there shown, each link comprises upper and lower plates 11% and 115 each plate having at each corner thereof an arm 116 an intermediate portion of which is curved outwardly, as shown at 117, and the outwardly purved portions of the corresponding arms of "the two plates are opposed one to the other to provide a substantially circular recess in which is mounted a ball bearing 118, which is firmly clamped within the recess by means pf a screw 119 which draws the ends of the two armsv together, the body portionsof the plates being riveted one to the other. These ball bearings are shaped to receive the ends of the pivot pins 112 and 113 and thus establish the connection between the links and the respective bars. In order that the proper amount of initial load may be sealed in the unit actuated lever 85 thereafter controlled by the operator as condition require, that lever is equipped at its right hand end, that is, the and opposite its connection with the indicating member, with a balance weight 120 which is screw threaded onto a rod 121 mounted in an opening in the adjacent end of the lever. This rod 121 is free torotate in its bearings inthc lever but is held against endwise moverelative to the lever by means of'a collar 122 secured to the rod and seated in an opening or recess in the end of the lever, in which it is retained by means of a plate or clip 123. The outer end of the rod 121 errtends beyond the end wall of the cabinet and is provided with a knurled head or knob 12% by means of which it may be actuated to impart lengthwise movement to the balance weight 120. This weight is held against rotatory movement by means of a pin 125 extending into a longitudinal slot 126 formed in the side of the weight 120.

A counterbalance is provided for the unit lever 85 to oppose the weight of the unit as applied to that lever. This counterbalance may take any suitable form but, in the present instance, I prefer that it should be of such a character that its operation will not be affected if the mechanism is not mounted in a level position because, as has been explained, the mechanism is portable and it is undesirable that it should be necessary to accurately level the same each time its position is changed. A spring couterbalance satisfactorily fulfills this requirement and I have therefore applied to the lever 85 a counterbalancing spring 127. This spring is shown as a coiled spring and one end is secured to a plug 128 which is screw threaded into the coils of the spring and which is adjustably mounted on the upper end of a rod 129 by screw threading that rod into the plug and providingthe same with a locknut 130. The lower end of the rod 129 is secured to the spacing plate 9, the rod having a head 131 arranged beneath that plate to hold the rod against upward movement. The tension of the spring is definitely determined or sealed to'a definite standard on a sealing apparatus before the spring is assembled in the device. This is accomplished by adjusting the plug 128 within the coils of the spring to vary the number of efi'ective coils, thus varying the power of the spring. After the'devi'ce is assembled the plug is adjusted lengthwise of the rod when sealing the weighing mechanism and is secured in this position by means of the lock nut 130. The opposite end of the spring is connected with a tape or ribbon 132 which is rigidly secured at its other end to a cam 133 rigidly but adj ustably connected with the supporting member 64 for the unit indi cating member. As here'shown, the upper end of thespring is provided with a hook shaped portion 13% which is hooked through a clip 135 secured to the lower end of the ribbon 132. The cam 133 is rotatably mounted onthe trunnion 69 which is secured to the supporting member 64 and is provided on opposite sides of its axis with shoulders 136 which are engaged by screws 137 mounted in lugs 139'forming a part of the supporting member 64, thus rigidly connecting the cam with the supporting member but permitting it to be adjusted with relation thereto. Pref- 'erably the cam is provided with an extension 140 lying on that side of its axis opposite the body thereof and which serves to counterbalance the weight of the cam. t will be noted that the counterbalancing spring is connected with the unit lever through the medium of the supporting device for the unit indicator instead of connecting it directly with the lever. The reason for this is that the unit indicating member 22 has an oddity of spacing, that is, it is moved different distances by the successive application of additional articles of the same weight, and this oddity oi" spacing or uneven movement cannot be secured with a standard type of spring attached directly to the main lever. A spring such as is here shown has an evenly graduated movement for equal increments of applied power which would not accommodate itself to the unevenly graduated movement of the indicating member. The indicating member being connected with the main lever of the unit balance it necessarily follows that the graduations of movement of that lever will also be unevenly spaced, thus prohibiting the attaching of this spring directly to the lever. By connecting the spring with the main lever of the unit balance through the supporting device for the units indicator an arrangement is provided which will accommodate itself to the uneven movements of the indicating member and lever. The indicating member has a very much greater angular movement than has the lever and thus it is possible to obtain a suflicient range of variance of leverage in the connection of the spring to the indicating member and in the connection of the indicating member to the lever to cause the evenly graduated movement of the spring to be converted into the unevenly graduated movement required by the indicating member. This conversion of the evenly graduated movement of the spring into the unevenly graduated movement of the indicating member is accomplished by varying the power of the arm to which the spring is attached and also the power of the arm to which the lever is attached. These variations in power may be produced either with irregularly shaped cams serving as arms or with arms having pivotal connections with the spring and with the lever, such arms being set radially to give the variations required. In the present construction I have utilized the cam 133 as the arm to which the spring is attached and an arm with a pivotal. connection for attachment with the lever, but it will be understood that these connec tions may be of anysuitable character.

lVhen a spring counterbalance of this character is employed it is desirable that the pivoted supporting member and its cooperating parts should be balanced about their common axis, as otherwise a pendulum action might be set up which would interfere with the proper operation of the device whenever it was not setting in a level position. ,To this end the supporting member 64 is provided with balance weights 184 which are adjustably mounted on screws 185 anchored in the supporting member (34. Ordinarily the cam 133 would be included in the assembly of parts associated with the supporting member 64 and balanced about the axis of that member. However, should the range of adjustment of the cam 133 and arm 70 relative to the member 64. be relatively large, then it may be desirable to balance the cam and the arm each separately from the supporting member 6 1. The adjustment of the screws 137 which control the position of the cam and of the screws 73, which control the position of the arm 70, even it these screws are moved in either direction to their extreme positions, will not throw the assembler unit out of balance sufficiently to have any appreciable effect upon the operation of the computing mechanism.

The manipulation of the unit indicating member may be automatically accomplished through the weight of the unit as above described; or it may be manually accomplished by setting the same to a position significant of the weight of a unit expressed in pounds and ounces, in which case the unit balance might be dispensed with and the weight of the unit determined on a separate weighing mechanism; or the indicating member may be set according to an index number, or the like, which has previously been determined by the use of the unit balance. here articles of the same kind are being frequently counted it may be desirable to provide means for manually setting the unit indicator without the necessity of using the unit balance. As shown in Fig. 1, the device is provided with a fixed chart or scale 150 over which the unit indicating member moves and which is graduated according to pounds and ounces, as shown at 151, to indicate the weight oi. the unit, and is also provided with a series of arbitrarily selected numbers 152, which may be termed index numbers. lVhen a unit of a given article is placed in the unit receptacle the operator may note the weight of the unit, or preferably the index number with which the unit indicating member registers. Thereafter when it is desired to count articles of the same kind it is only necessary to move the unit indicating member into registration with this same index number and the result will be the same as if a unit had been actually placed in the unit receptacle. To accomplish this adjustment of the unit indicating member I have mounted on the base 1 a bracket 153 which is provided with parallel side walls between which is pivotally mounted a bell crank lever 15 1. This lever consists of two members arranged side by side and mounted on a pin 155 which in turn is journaled in the side walls of the bracket 153. A spacing sleeve 156 is mounted on the pin 155 between the two members of the lever and, in the present instance, is rigidly secured thereto by as the by-pass type.

head or cap 166.

at 169, and is seated in a pivotally connect-ed toits free end a connecting member or bar 158 which extends upwardly therefrom through the spacing plate 9 and is provided atits upper end with a hook shaped portion 159 arranged to engage a pin orstu'd 160 carried by the lever at the unit balance. A spring 161 acts on the bell crank lever to hold the same normally in its retracted position with the connecting bar 158 out oi engagement with the lever, so that that bar will not in any way interiere with the free movement 01" the lever. Pivotally mounted between the upper ends of the upright arms oi the bell crank lever is a contact block 162 with which engages the end of an actuating rod 163 which is screw threaded into the upper portion of the transverse wall 01": the bracket 153 andwhich extends outwardly beyond the cabinet of the machine where it is provided with an operating knob 16%. lVhen it is desired to set the unit indicating member manually the knob 16% is turned in a clockwise direction, causing the rod 163 to move the bell crank lever about its axis andcausing the hook shaped portion of the bar 158 to engage the pin 160 on the lever 85 and thus move that lever downwardly and adjust the unit indicating meiber to the desired position, that is, into registration with the predetermined index number on the fixed chart 150, or into a position which may have been predetermined in any suitable manner. When the indicating member has thus been set it will remain in its adjusted position so long as the position 01" the actuating rod 163 is undisturbed and successive lots otarticles of the same kind may be counted without resetting the units indicating member. When the count has been completed and the actuating rod 163 is retracted the counterbalancing spring 127 will restore the units lever 85 to its normal position and the spring 161 will move the bell crank lever and the bar 158 to their normal positions, thereby again lifting the hook shaped end of the bar 158 out of engagement with the pin 160.

' The oscillations of the unit balance are preferably controlled by a dash pot connected with the lever 85 and, in the present instance, 1 have utilized a dashpot of what is known This dash pot comprises a cylinder 165 mounted on the base 1 and closed at its upper endbya cylinder Mounted within the cylinder is a piston 167 with which is connected.

'a piston rod 168 which extends upwardly through the cylinder head 166 and is connected at its upper end with the lever 85. To this end the upper end of the piston rod is substantially spherical in shape, as shown correspondingly with the main lever of the unit balance and shaped socket formed in a block or bearing member 170 which is carried by a plate 171 rigidly secured to spaced lugs 172 carried by the lever. The cylinder head or cap 166 is provided about the opening through which the piston rod passes, with a flange 173 to form a drain chamber, that is, any liquid which may be carried through the opening in the cap along with the piston rod will be caught in this chamber and returned to the cylinder. Further, this chamber is so shaped that a two-part plug, such as an ordinary cork divided into halves, may be in-- sorted in the chamber about the piston rod to seal this opening and prevent loss of liquid during the shipment of the machine. The piston or plunger 167 is here shown as cupshaped with a slightly tapered or conical upper surface and is provided near the apex thereoi with vent openings 17%. The piston or plunger is preferably made of considerable length so as to give a relatively high resistance to its movement, as this resistance is largely controlled by the length of the plunger. This is due to the fact that the fluid escaping betweenthe walls of the cyl inder and the plunger orpiston must travel a longer path and is subjected to a greater resistance in its movement, thus retarding the movement of the fluid and oliering a greater resistance to the movement of the piston. The vent openings 174 are not of suilicient size to permit of any material quantities of fluid to pass through the same but are for the purpose of releasing air bubbles which may become pocketed inside the plunger. The cylinder 165 is provided near its upper and lower ends, and above and below the piston, with ports 175 and 176 which are connected one to the other by a by-pass or exterior conduit 176 through which the fluid from that end of the cylinder toward which the piston is moving must flow in order to reach the opposite side of the piston, the clearance between the piston and the cylinder being sufiicient only to permit the passage of relatively small quantities of this fluid. The flow of the fluid through the by-pass is controlled bya valve or cut-oil which serves to the cut-oil member 177. Consequently the rotation of the rod 179 will move the cut-oil orvalve member-17 7 into or out of the by-pass 176, according to the direction inwhich the, rod is rotated. The rod preferably extends beyond the outer wall of the cabinet where it is provided with an actuating knob 182. The end of the boss 17 8 may also be provided with a stufling box 183 to prevent leakage of the liquid about the rod 179.

The operation of the device will be readily understood from the foregoing description and may be set it th briefiy as follows: When a mass of articles of like weight is to be counted these articles are first weighed on an ordinar weighing scale to determine the exact weigat of the a lies, exclusive of the weight of the container or other tare weight. The operator then turns the pointer 51 to the weight indication on the dial 53 corresponding to the weight of the mass of articles, say, for example, 4 18 pounds. This movement of the pointer serves to move the chart .21 also into a position corresponding exactly to the weight of the mass of articles. The operator new places one or more of the articles which are to be counted in the unit receptacle 98. If a single article does not impart sutlicient movement to the unit in dicator 22 to cause the same to intersect the center line on the chart 21 he adds additional articles to the unit, following the indications on the chart 21, which, as has been explained, designed to effect computations based upon units consisting of 1, 2, 5, 10, 25 and 50 ar ticles. Assuming that five articles placed in the unit pan effects the intersection of the unit indicating member with the center line of the chart, the operator then takes the reading from the chart using the numerals appearing in the 5 column or series. The particular graduation on the chart which is intersected by the unit indicating member indicates the number of articles in the mass and the significance of this graduation is indicated by the corresponding number in the selected series, that is, column 5; say, for example, 875, which would mean that there Wei-e875 articles in the mass which was being counted.

. .,.with, as, for example, 5107, so

.t the operator will know in what column in c rt to take his reading.

,7 if the operator desires to make up a lot of articles say, for example, 750, he first c ,owest denomination in which the num her "350 appea rs, which is column 5. He therefore laces five articles 111 the unit receptacle and then adjusts the chart 21 by means of the bodiment of my invention I wish it to be understood that I do not desire to be limited to the details thereof as various modifications may occur to a person skilled in the art.
